Abstract: PURPOSE:To smoothly purify air with satisfactory timing, by providing an auxiliary smoke detector in the vicinity of a rear seat, and by selectively changing over the capacity of purification between a high level and low level in accordance with a drive signal associated with the detection of the auxiliary smoke detector, and drive signal from a front seat smoke detector. CONSTITUTION:When the level of a smoke detection signal from a front seat smoke sensor 30a, is higher than a predetermined level, a judging circuit 40a generates a judging signal to energize a transistor 50a so that a relay 60 excites a solenoid coil 61 to close both switches 62, 63. With this arrangement, the supply voltage of a motor M is decreased by a value corresponding to a resistor 80 so that the motor M is rotated at a low speed to give a low purifying capacity. Operation is also performed at the low purifying capacity when a rear seat smoke sensor 30b detects smoke. When both sensors 30a, 30b detect smoke having levels higher than predetermined levels, a circuit for short-circuiting the resistor 80 is established so that the motor M is rotated at a high speed, and therefore operation is performed at a high purify air with satisfactory timing.
